If you have a good relationship with Discover, hit them up on chat and ask if your account has any promo offers. It's been documented here that you can get up to 12 months 0% on existing accounts if you ask.
+1 DW got a year of cashback match when they forcibly product changed her to Discover it, then she got a year at 0% after having her account open for 22 years when I did chat to ask for her APR to be lowered.
Another option with Disco is to check your pre-quals, app for one that you are solid on, then call and ask to transfer some of your limits on the old Discover to the new one.
